REVERSIBLE DRIVE-CHAIN LINK.

. Specification of Letters Batent.

Patented Dec.21, 1915.

Application filed march 20, 1913. semi No. 755.768.

To all whom it may concern) Be it known that I, GEORGE A.

Northumberland, in the county of Northumberland and State of Pennsylvania, have invented certain new and useful Improveitsobject to providea link of this character which embodies novel features of construction whereby the link may be assembled in parts for coupling, thereby prolonging the life of the chain and reducing repairs to a minimum. 7

A further object of the invention is to provide a reversible chain link of this character which is simple and inexpensive in its construction, which can be readily removed from the chain and again applied thereto in a different relation so as to present fresh and unworn parts for coupling, and which can be easily and quickly placed in position or removed therefrom as may be required.

A still further object of the invention is to provide a chain belting which is formed of reversible and interchangeable links and which will be specially useful in connection with conveyers of all kinds, dredges, and.

other similar machinery in which the chain belt is subjected to heavy wear such as necessitates frequent repair and replacing of the links.

WVith these and other objects in view which will be apparent to those familiar with the art, the invention consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

A few practical embodiments of the invention are suggested in the accompanying drawings, in which- Figure 1 is a plan View of a series of reversible links which have been properly assembled to provide a portion of a chain. Fig. 2 is a detached view of one of the individual chain links. Fig. 3 is a view similar to Fig. 1, showing a slight modification of the invention. Fig. 4 is a similar view showing a still further modification of the invention.

Specifically describing the embodiment of the invention shown by Figs. 1 and 2 of the drawings, the characters A designate the in- JoNns, a citizen of the United States, residing. at"

dividu'a-l'links as an entirety, the various links'being shown in Fig. 2 as assembled to form a chain section; Each of these links comprises a polygonal brdy portion, a portion of the sides of the polygonal body portion forming pintles 1, while other sides of the polygonal body portion are formed with knuckle hooks 2. The links A are preferably rectangular in shape, and in this embodiment of the invention, the pintles l and. knuckle hooks 2 are oppositely"'disposed, there being a pintlel directly opposite each of the knuckle hooks 2.

In assembling the various links A to provide a chain section," one of the knuckle A hooks 2 of each of the links A is brought into engagement with the pintle l of an adjacent link, the pintle 1 of the first mentioned link opposite the said knuckle hook being adapted to be brought into engagement with a knuckle hook of the other adjacent chain link. The chain may then be used in the usual manner until the coupling parts thereof become worn. Instead of replacing the Worn link with an entirely new link, as is usually necessary, the worn llnk may be merely removed from the chain and again applied thereto in a different relation so as to present for coupling fresh and unworn parts. The previously unused pintle 1 and knuckle hook 2 would be placed in operative position, the worn members assuming an inoperative position.

A slight modification is shown in Fig.3 of the drawings, in which the knuckle hooks 2 are provided at the ends thereof with the reinforcing ribs 3. The individual links A however have the same general construction, being rectangular in shape, two adjacent sides thereof providing pintles 1, while the remaining sides are provided with knuckle hooks 2. The various links are assembled in thesame manner, and the position of the individual links may be shifted at any time to relieve the worn parts from service and present fresh and unworn parts for coupling.

A still further modification is shown in Fig. 4, in which the individual links B have a rectangular or polygonal formation, a portion of the sides of each link being constructed to form pintles 4, while other sides are formed with the knuckle hooks -5. The pintles 4 and knuckle hooks 5 are arranged in oppositely disposed pairs, and where the links B have the rectangular shape, as

shown, there is one oppositely disposed pair of pintles and'one oppositely disposed pair of knuckle hooks 5. In assembling the 7 the fresh and unWorn pintles 4L and knuckle hooks 5 into a coupling relation.

I claim:

1. A drive chaincomprising aplurality of individual and separable rectangular link elements, each having any two sides thereof constituting pintle members, While the other sides are provided with knuckle hooks for "Copies of this patent inay be obtained for five'cents each, by addressing'the Commissioner orraamsj When the coupling elements of detachably engaging and receiving the pintle members of'adjoining'links, said links be- I ing interchangeable and replaceable to efiect the coupling of; difierent pintle members and knuckle hooks to present fresh unWorn parts. V

2. Aremovableand reversible link for drive chains, comprising a polygonal body portion, any two sides of said polygonal body portion forming pinue members,while the other sides are provided With knuckle hooks, different knuckle hooks and pintle; members being adapted to be presented for- 7 coupling Withadjacent links by shifting the position of the link.

In testimony whereof I hereunto aifiX my signature in the presence of two Witnesses.
